FSU running back Wilder out with cracked rib

James Wilder ran 13 times for 69 yards and a score in Monday's physical simulated game.

TALLAHASSEE — FSU running back and former Plant High star James Wilder Jr. will not play in Saturday's spring game and will be out for the rest of spring practices with a cracked rib, coach Jimbo Fisher said Wednesday.

GAINESVILLE — Gators defensive line coach Bryant Young resigned, saying he wants to spend more time with his family.

Young, 41, had been on coach Will Muschamp's staff since 2011. He is married with six children, including a newborn.

"I have come to the realization that it is time to invest more in my family during this fleeting season in life," said Young, who had a 14-year NFL career with the 49ers. It is unclear whether Muschamp will replace Young or disperse his responsibilities.

Clowney ailing: South Carolina All-American defensive end Jadeveon Clowney, who is suffering from a concussion and neck and back pain after a practice collision last week, is expected to be out for Saturday's spring game and could be shut down from further spring practices, ESPN reported.
